And now for something different - Sporadic E propagation in 2 minutes (ish).
If the comments are encouraging, there'll be more 2 minute-ish videos! Feel free to suggest topics.
Sporadic E propagation is a type of radio wave propagation that occurs in the E layer of the ionosphere.
The E layer extends from about 90-120km above the earth’s surface.

Fantastic short video showing an easy to understand how the six metre band can be active for working long distances, and how quickly it can fade. As always, you need to be at your radio to catch these openings. Well presented informative video.
